This shorter gummy fin really works well for River running and skipping over the inevitable rock. It doesn’t stop you cold, but rather bends and conforms to get you through, and I don’t believe it could damage your fin slot as the longer ridged fin might. And it beats the heck out of going finless!

Not sure about the fin... haven't had it on the water yet. But I did unsubscribe from hala emails before receiving a request to review this product... so... let's say three stars, because of the lack of execution on my marketing preferences.

I use it for swamps in Mississippi that have a lot of shallow logs and stumps to get past.

Fin works great. Replaced a longer carbon fiber fin that tracked very well but didn't work well in rocky whitewater. Gets through shallow "boney" sections of whitewater perfectly, and despite the flexibility, tracks very well.

Exactly what I needed. Was out on the river last week and scratched up my hard plastic fin. I didn’t want to risk ruining my fin box going forward so I decided to purchase this gummy fin and use it just Incase I hit another rock. Works great.
